Oral-hygiene/dentifrice preparations which protect dental enamel

Abstract

Oral hygiene/dentifrice preparations contain a combination of fluoride or monofluorophosphate and phosvitin which counteracts demineralization of dental enamel. These substances act synergistically to help prevent demineralization of dental enamel. The concentration of fluorine compounds and phosvitin in the preparations is chosen so that, when applied, a concentration of at least 0.01 wt.% of dissolved fluorine and at least 0.01 % of phosvitin is present in the buccal cavity.

The invention claimed is: 
     
       1. Oral and dental hygiene compositions, comprising a combination of fluoride or monofluorophosphate and phosvitin or soluble salts thereof in such a quantity that, when used in the oral cavity, a concentration of 0.01 to 0.2% by weight of dissolved fluorine and 0.01 to 0.4% by weight of phosvitin is present. 
     
     
       2. Oral and dental hygiene compositions as claimed in claim 1 in the form of a toothpaste or a gel, comprising silicas or aluminum oxide trihydrate as an abrasive and polishing component. 
     
     
       3. An oral and dental hygiene composition as claimed in claim 1 in the form of a mouthwash, wherein, in its in-use concentration, the mouthwash contains 1 to 10% by weight of ethanol.
